Red Bull has endured a difficult start to 2014 with reliability issues plaguing the team across the opening two four-day tests.
McLaren driver Kevin Magnussen also confirmed that he will drive on the first and third days of the test for the team, with Jenson Button piloting the MP4-29 on the second and fourth day.
Lotus has confirmed their schedule for the final pre-season test, with Pastor Maldonado running on the opening two days.
Sergio Perez will kick off proceedings for Force India before handing over to Nico Hulkenberg for the final two days.
